' Specification of Letters Patent.

A pli ation fil d November 2'7, 1899. Renewed August 2, 1906. Serial No. 328,962

Toall whmn it mlrty concern.-

Be it known that 1, Louis W. SOUTHGATE, a citizen of the United States, residing at Worcester, in the county "of Worcester and State of Massachusetts, have invented a new and useful Multicolor-Printing Mechanism, of which the following is a specification.

This invention relates to new and improved mechanism for multicolor printing.

The principle on which the invention works is as follows: A printing plate or form is prepared. and the same is placed on asuitable base or carrier, cooperating with which is an impression member to force or press the material to be printed against the printing plate or form. Separate color-design plates are prepared, generally three in number, each color-design plate being designed to be used in connection with one of the distinct colors used. These color-design plates have raised or relief surfaces corresponding in height and position to theparticular application which is to be made of the These color-design plates are secured to an integral'carrier or base, which is entirely independent of and distinct from the carrier .or base for the printingplate propei'. A plurality of ink-fountains are employed in connection with the carrier or base for the color-design plates. An inkfountain is employed for each color.' Ink spreading rolls are arranged between the ink-fountains and the color-design-plate carrier or base, and suitable cam devices are provided, so that the plate-inking rollers will be raised and lowered melativelyto the carrier or base which carries the color-de'- ceptive surface on which the various colorv designs from the color-design platesare registered together lengthwise and widthwise to make up a positive of the complete multicolor design-that is to say, in practice the d sign or designs of each of the color-design plates consists of one or more irregular shaped or outlined figures or spots, each detransfer device.

fining and controlling a particular application of the color manipulated by the parti cular color-design plate; The arrangement before described is such that these various spots 01; designs coming from the plurality of the color-design plates will be registered together -lengthwise and widthwise on the transfer device tomake up a positive of the complete multicolor design. The colors may be blended, if desired, as Well as registered by having the designs overlap on the The active transfer-surface of the transfer device is thus equal to and is arranged to register with and ink the printingplate. The operation with this construction is substantially as' follows: The color-design plates will be properly inked, as before described, the design 'of all the color-design plates will be transferred to Patented April 23,1907. A v

the transfer-device, the. printing-plate car- .rier and the transfer device will then move one relatively to the other, so that the trans-- fer device will properly ink the printingplate, so that the various color designs properly blended or matched will be applied to the printing-plate. The impression member will then press the material to bev printed onto the pro; erly-inked printingplate, and irf this Way the multicolor impression will be made.

A separate mechanism, consisting of a separate plate for black ink, an ink-fountain, a set of inkingerollers, and. a transfer member,

- is usually arranged. in connection with the above-described color-printing mechanism to apply black ink to the printing plate or form, so that the impression made will not only be a color im ression, but will have black matter, as rea ng-matter, thereon.

The previously-described mounting of the' color design plates 'on a single integral carrier independent and separate from the printing-plate carrier permits of the application of the invention to almost every variety of printing-press and permits of the designing of machines which will operate at high speed.

i Fig. 6 is' a view similarto Fig. 1, illustrating and end elevation, of the color-design-plate' carrier, illustrating the arrangement ofthe color-design plates and plate-inking rollers. Fig. is a'view similar to Fig. 1, illus-.

trating a slightly-modified form of press.

one application'that maybe made of my in- 'vention to a rotary printing-press printing on a continuous web and printing not only one page or sheet in colors, butone or more pages-- or sheets in black or coloredinki Fig. 7 is an underneath plan view of the printing-plate carrier shown in Fig. 6; and Fig. 8 is a view similar to Fig. 6, illustrating the arrange-. ment in arotary sheet-printing press when it is desired to print one page in colors and one or more pages of a signature in black or onecolored ink. A 1

Referring now to the first and second sheets of drawings, I will describethe application therein'shown, of my invention.

A represents an impression-cylinder which has the usual grippers a and to'which sheets are fed, as from feed-boardB. The printed sheets are taken from theimriression-cylinderby the usual stripper-fingers 10 and pass out on any of the usual delivery-tapes 11. The impression-cylinder may be of the tworevolution pattern, the stop-cylinder pattern, or the drum-cylinder pattern. The tworevolution is shown and is preferred for large work, while thedrum-cylinder. is preferred for small work. I

C designates imprinting-plate carrier. The same is designed to carry the printing-plate 0. One convenient. relative arrangement between the impression-cylinder and printing plate carrieris to make the impression-cylinvder one-half the size. ofthe printing-plate carrierand touse two-thirds bfthe surface of the impression-cylinder for the .largest size sheet that is to'be manipulatedand one-third of the surface of the printing-plate carrier for the largest plate that is to be used w E designates the oolor-design plate icarrier. This color-design-plate carrier is separate and distinct from theprinting-plateoar rier. The same is capacitated to receive three color-design plates e e ei of the size of the printing-plate c.

D designates a transfer-cylinderwhich hasa soft or receptive surface and which is arranged between the printing-platejcarrier C and the color-design-plate carrier E. The transfer-cylinder has a surface area equal to thelargest printing plate or form to be used and is arranged so that the various color outlines or figures from the color-design plates will be registered together circumferentially and axially and so that its active surface will register withv and ink the rinting plate or form. The color-design-p ate carrier and the'printing plate carrier are driven by any suitable gearing, as the ordinary spur-gearing, to turn inthe same direction. The

: transfer-cylinder makes as many revolutions relatively to thecolor-design-plate carrier E design-plate carrier is adapted to receive.

- as the number of color-design plates said color- Thus in the specific application now under consideration as the color-design-plate carrier has three plates the transfer-cylinder D will make three revolutions for each revolu- 'tion of the colorfdesignlate carrier. Co operatinggwith'the c0loresign-plate carrier E 1s an inking apparatus for each color-de- "sign platei The inking apparatus for the color-design plate 6 consists of aninksfountain F, an inkcarrier roller h, a distributer-roller g, and two form or plate inking rollers f f. The inking apparatus for each of the other two color-designplates is of the same pattern and is referred to by the same reference-letters,

except that'the inking apparatus which is used for color-design late (2' is referred to by reference-letters F '&c., and the inking a paratus that is used-for the color-design gate 6 is referred to by the reference-letters 3 &c. The plate or form inking rollers are journaled in arms or brackets 12 12, which are hungon the shafts of the distribu ter-rollers, as shown in the second sheet of the drawings. *The distributer rollers arerigidly journaled in the side frames or in suitable brackets inthe ordinary manner. ()n theshaft of each of the plate-inking rollers is arranged a roll or .Wheel 13. Three cam' grooves are out in each end of the color-design-plate carrier E to correspond with the .position ofthe respective color-design plates. Thus-,for example, grooves 14 correspond in position with the color-design plate e, grooves 15 with the color-design'pl'ate e, and grooves I oo 16 with @the color-design plate. e The Wheels 13 on the plate-inkingrollersfif are set to engagethe grooves15; the 'wheelsfon the plate inki'ng rollers f? the grooves 16,

- and the wheels on the plate-inking rollers f I fthe groovesl. .The. grooves and wheelsare'preferably' duplicated at each end of the color-design-plate carrier. Each distributer'- roller and its two form or plate inking rollers may be inserted in the press as one set, the

brackets 12 12 being kept in. comparatively the same relative position by springs 17, arranged between the gbrackets. -The form inking or plate rollers are also forcibly pulled toward the center of the polor designepl'ate carrier by hooks 18, which engage the brackets -12 12 or ..the shafts of the plate-inking rollers and which connect by heavy springs 19 to studs 20 on theinside of one of the framesf These hooks are used so that the .inking devices can "be'readily taken out or ut in place, as desired. By this described arrangement'itwill be seen that the form or Y plate inking rollers of each set will only sup ply ink to one' of the color-design )lates. Thus, for example, the form-inking rollers f f will turn about the diStributer-roller g to contact with the colordesign plate e as the same passes the first inking .tpparatus by reason of the cam-grooves 14 allowing the springs 19 to pull them into operative position, but when the plate 6 passes the first 1o inking apparatus the smooth portion at' the end of the color-design-plate carrier-will cam or raise the plane or form inking rollers f f clear of the color-design-plate carrier, so that the first ink-fountain will only supply ink to i5 the first color-design plate 6.

The operation of this mechanism before descfibed is such that the color design plates will be properly inked by the rotation of the colordesign-plate carrier or cylinder, and if 26 the three primary colors are usedas, for example, red in the first fountain, blue in the second. fountain, and yellow in the third fountainthe color-design-plate carrier, with its three plates, will be adapted to give fine 2 5 shadings and blendings to make up almost any multicolor design. The designs of all the color-design plates will be transferred to the transfer-cylinder D, and the transfercylinder Will apply the three colors registered 30 and blended, if desired, to the printing-plate a, so that the same will be properly inked to give a properly matched or blended multicolor impression. The operation will be as rapid as sheets can be fed to the impressioncylinder, as the cylinders can be made of convenient size. If it is also desired toapply black ink to the printing-plate, a separate carrier K may be arranged to turn in the same direction as the printing-plate carrier 0 and the color-designplate carrier. A plate 7c may be secured thereon and may have portions in relief which correspond to the application which is to be made of the black ink. An ink-fountain F, inkcarrying roller h, distributer-roller g, and plate or form inking.

rollers f f i are arranged to properly ink the plate lc. A transfer-cylinder L is arranged between this third carrier K and the printing-plate carrier, said transfer-cylinder L being the .same size as transfer-cylinder I). By this arrangement the black design will be properly applied by the transfer-cylinder L to the printing-plate 0, so that the impression made will not only be a multicolor impression, bnt will have portions thereof, as reading-matter, iii black. This mechanism for applying the black ink is preferably arxranged to apply the blackink to the printing-plate after the latter has received its ap- 0o plication of colored inks, so that there will be a'n'impression taken from the printing-plate before the same again comes around to the transfer-cylinder which applies the colored inks, so that theblack ink will be prevented from working into the colorfountains.

I generally provide a cleaning device for cleaning the printing-plate between each impression and inking. This cleaning device may consist of a soft cylinder M, turning in connection with the printing-plate carrier to remove any surplus ink therefrom after impression. This cylinder M bearson a blanketor apron N, whichis trained around suitableguide-rollers n n it and. is held in place by a' roller n. The blanket N-is preferably he'ld stationary, so as to take up the surplus ink from the cylinder M, and is shifted from time to time so as to present afresh surface. In this way the printing-plate will be cleaned after each impression and before the next inking.

The parts A C L K and C M and C D E are connected to turn together by spur-gearing, which is not deemed necessary to detail in this case for a clear understanding of the in- Vention.

The before-described mechanismconstitutes a very simple and rapid multicolorpress in which a multicolor impression can be made or a multicolor impression with part thereof in black, or by putting some ink besides black in the fountain F the impres-' sion may be made four-color or three-color, with the reading-matter or matter printed from plate 7c in a separate color.

In Fig. 5 I have shown a slightly-modified form of the foregoing machine. In this modification the plate 76 is arranged on the printing-plate carrier C. The ink is taken therefrom by the transfer-cylinder L and put on the printing-plate c. The inking apparatus for the plate is is arranged as shown, and the form-inking rollers f f are allowed to contact only with the plate 16 by using the mechanism illustrated in the second sheet of the drawings. The plate It in this modification is preferably set a little below the plate 0, so that the same will not contact with the impression-cylinder A or the transfer-cylinder I), and the transfer-cylinder -L is arranged in sliding boxes 21 which are controlled by springs 22 to contact both with plate 7c and printing-plate 0.

Another advantageous Way my invention can be applied to a rotary press is to make .the carrier which carries the printing-plate carry one or a number of other plates which will print in black. This construction is shown in the fourth sheet of the drawings in Figs. 6 and 7-. In this construction the color-design-plate carrier E is made to carry four plates, one of which may be the plate k of the previous devices, and this carrier has four fountains cooperating therewith. The printing-plate carrier 0 has not only the plate 0, which is to make the multicolor impression, but three other plates 0 c c secured thereto. In thiscase the transfer-cylinder D is made one-fourth the s ze of the cylinders C and E. The same is arranged in am. 23, which are hung about the center of the cylinder E and I black, if desired, by the transfer-cylmder .D,

ranged between said arms and fixed studs'25 An inking apparatus is arranged in connection with the plate-carrier C to inkthe plates 0 c 0 This inking apparatus mayconsist of a fountain F", 'four form or plate inking rollers f twodistributer-rollers 9 two inkcarrying rollers h, an ink-drum h, and a ductor h. This inking apparatus is preferably made double, as shown, on account of the large amount of ink it has to supply. The form or plate inking rollers f 4 f are mounted as shown in the second sheet of drawings and are controlled by grooves 30, which extend around the cylinder C in position to re ister with the plates 0" 0 0 The transfercylinder D is allowed to contactv only v with the plate 0 bymeans. of wheels 28,. mounted on the shaft thereof, which engage grooves 29, cut in the'cylinder G to register with said plate 0. The impression-cylinder A in this modification is made to present acontinuous web w by means of web-guides 26 and 27. In this mechanism the ink-fountain last de-- scribed, arranged in connection with the printing-plate-carrying cylinder, has its inking-rollers controlled by the cam mechanism, so that the plate or plates on the print ing-plate-carryin cylinder which are to print in black wi be inked withblack over. their entire surfaces; but the color-printing plate 0 will riot be operated upon by-saidinking-rollers. This last plate 0 corresponds to the printing-plate of the previous devices, and the same will be inked in colors and which 006 erates between thecylinders'C and E. L, as shown, three plates for black ,printing and one for coloreprinting are arranged in this manner, a continuous web will be (printed with three pa es in blackmatter an the fourth page in co ored matter. This 1 is an advantageous arrangement for magazine or news aper-qwork. If 'des1red,'of

course the p atescarrier for the .-printing-' plates may be made to carry any number of printing-plates which are to give black impressions more or less than three, so that an desired signature'of pages can be obtaine with one or more pages thereof printing in colors.

"In t is arrangement the p ates are arran ed In Fig. v8 the samearrangernent is shown to extend only partway around the cylin ers ,C and E, so that time will be given for the feeding and delivery of sheets to and from the impression-cylinder. In the particular device shown the plates are'made to "cover' four-ninths of the surface of the impressioncylinders, and the transfer-cylinder D is pro- 'portionedto make nine revolutions foreach.

Plates smallerxthan those shown may be ar-' ranged on the respective cylinders by making the heads thereof comev to the same point where the heads of-the plate shown come.
